Answer:

-1.67

Explanation:

Price elasticity of demand using midpoint method can be formulated as below:

Price elasticity of demand = {(Q_2 - Q_1)/[(Q_2 + Q_1)/2]}/{(P_2 - P_1)/[(P_2 + P_1)/2]}, where:

<em>Q_1 and Q_2 are the volumes before and after price changes;</em>

<em>P_1 is initial price and P_2 is new price.</em>

Putting all the numbers together, we have:

Price elasticity of demand = {(50-100)/[(50+100)/2]}/{(3-2)/([(3+2)/2]} =

- 1.67

Note: Negative sign indicate that when price increases volume will decrease.

He stockholders' equity section on the December 31, 2009, balance sheet of Chemfast Corporation reported the following amounts:
Allisa [31]

Answer:

1.7900 shares

2.7300 shares

3.$22.95

4.$59

5.$6,300

6.$10.50

7.$791,000

Explanation:

The number of preferred shares=total par value of preferred shares issued/par value=$165,900/$21=7900 shares

The number of preferred shares outstanding is issued shares minus treasury stock=7900 shares-600 shares=7,300 shares

average issue price of preferred stock=(total par value+additional paid capital)/issued shares=($165,900+$15,400)/7900=$22.95

Average issue price of common stock==common stock amount/issued shares=$590,000/10000=$59

The treasury stock decreases stockholders' equity by the amount paid to repurchase the shares which is $6,300

Treasury stock cost $ per share=cost of treasury cost/number of treasury stock=$6300/600=$10.50

Total stockholders' equity in $=preferred stock+preferred stock additional paid in capital+common stock+retained earnings -treasury stock

Total stockholders' equity in $=165,900+15,400+590,000+26000-6300=$791,000

The bank is working to develop an efficient work schedule for full-time and part-time tellers. The schedule must provide for eff
Kitty [74]

Answer:

The solution is given below.

Explanation:

It is a practical, complex scheduling problem that can be easily modelled and solved as IP. Note that  part time and full time employees are paid at different rates. So, it is important that the bank operates to provide required service level (indicated by the number of tellers per hour) while  minimizing total cost due to staff salary.

We use x as full time and y as part time staff.

It would help if you construct a table as shown below to better analyze the problem before  attempting to model it. Red shows work hrs of full time staff and green is for part timers. Just follow  their work hour rules.

So, full timers have 3 options:  

(i) start at 9 – work till 1pm, take 1 hr break, then work 2 – 5 pm

(ii) start at 10 – work till 2pm, take 1 hr break, then work 3 – 6 pm

(iii) start at 11 – work till 3pm, take 1 hr break, then work 4 – 7 pm

that’s all… bank closes at 7 pm.

However, part timers don’t have 1 hr break. They work straight 4 hrs and leave. See green cells  above to understand their alternatives.

Now, decision variables should include this work hour information. Here goes their definition. You  must clearly define decision variables in exam, otherwise, the model is meaningless.

X9 = number of full time staff who start at 9 and follow the hour-related rule (no need to specify  more details; those are already undestood)

X10 = number of full time staff who start at 10 and follow the hour-related rule

X11 = number of full time staff who start at 11 and follow the hour-related rule

Y9 = number of part time staff who start at 9 and follow the hour-related rule

Y10 = number of part time staff who start at 10 and follow the hour-related rule

…. This way you define up to Y15.

You must also specify that:

Xi, Yi >=0, integers.

Objective Function:

Minimize Z = 105*(x9 + x10 + x11) + 32* (y9 + y10 + … + y 15)

You will need one “covering” constraint for each working hour. Both full and part-timers can “cover”  the duty of each hour. Look at the color-coded table (above) column-wise. The 9:00-10:00 hour can  be covered only by x9 and y9 staff; next hour by x9, x10, y9, y10 only,… and so on. So, the
